Film of quarry stone breaking by hand 1953 – possible location?

HF: Tymon Mellor has sent this extract from a longer Pathe film from 1953. It shows the lower end of a quarry adjacent to a road. Here a group of about twenty men and women are undergoing the final ardous process of breaking stones into aggregrate sized pieces using a variety of tools.

Can someone identify exactly where the quarry and workers were 61 years ago?Thomas Ngan thinks he may be able to. This cropped aerial photograph (1) from 1964 shows Taikoo Dockyard at the bottom. And in the centre what appears to be a quarry with housing very similar to that which appears at the start of the film.

Thomas adds, Try to look around the area using Street View:https://goo.gl/maps/Eg4NwThis shows the present day area between Quarry Bay and Sai Wan Ho, along one of the back streets. At the end of Tai Foo Street can be seen what looks very much like a disused quarry.

HF: I have seen this kind of stone breaking being done in various places but not in Hong Kong. Most notably in India on a bridge crossing a river in 1988. Huge river boulders were being very slowly broken up with chisels, wedges and sledge hammers.These large stones were themselves being broken up. And so on by about six different groups each responsible for reducing the size of the stone. The final stage was up on the bridge itself where a group of women and children were doing what you see in this film extract – creating gravel-sized stones. These were thrown directly on to the road and covered in tar.

Tymon has also provided a some background information to ‘permit’ quarries which the one in the film may well have been.

“Until the mid-1960s almost all the quarries in the [Hong Kong Island and Kowloon] district were small workings in granite, supplying the market for aggregate, roadstone and building stone. Aggregrate for concrete manufacture became important with the advent of the large-scale housing developments from 1954 onwards. About 59 small-scale ‘permit’ quarries provided crushed stone for aggregrate use, but major mechanisation and large-scale working were introduced by the Government in the 1960s in their new quarries at Diamond Hill and Mount Butler.” Source: Geology of Hong Kong Island and Kowloon – Hong Kong Geological Survey Memoir No 2 Dec 1986 – Chapter 9
